Problems solved by technology

[0005] (1) The existing blockchain only completes the transfer of digital assets owned by the transferor to the receiver, which cannot meet the transaction needs in the real environment, and lacks the payment process corresponding to asset transfer
[0006] (2) There is a lack of protection for digital asset transfer operations on the chain. After the transferor of the transaction initiates the asset transfer transaction, he cannot guarantee that he will receive the price paid by the receiver. There is a transaction risk
[0007] (3) Lack of interactive capabilities for off-chain operations, all operations can only be completed on a closed chain, unable to support the process of off-chain payment, and unable to control the transaction risk of the entire process
[0008] (4) The digital asset transaction process of the prior art relies on a third-party platform, and there are third-party platform credit and security issues

Embodiment 2

[0072] Embodiment 2: Both parties to the transaction need to do some preparatory work before the transaction, such as logging into their respective asset application terminal systems, querying their respective on-chain assets, etc. In the second embodiment, the transferor inquires the on-chain assets it holds through its asset application terminal system, so that the transferor can select the asset category and input the amount of transferred assets based on the acquired on-chain asset query result information. The recipient checks through its asset application terminal system whether its corresponding asset information to be transferred has been generated in the asset ledger system, so that the recipient can start making off-chain payments. The specific implementation is as follows:

Embodiment 3

[0097] Embodiment 3: Since the confirmation information provided by the transferor with its own signature, or the receipt certificate can also be used as the trigger condition of the smart contract execution layer module to execute the second smart contract in the transfer instruction of the assets to be transferred, it is implemented In Example 3, the method for transferring assets on the chain through off-chain settlement in the embodiment of the present invention is described by taking the transferring party sending an instruction to transfer assets to be transferred on the chain as an example. The specific implementation is as follows:

Such as Figure 4 As shown, the main process of asset transfer through the on-chain asset transfer system of the off-chain settlement in Embodiment 3...

Embodiment 4

[0102] Embodiment 4: If the transferor has initiated an asset transfer transaction and forms the asset to be transferred in the asset ledger system, but the receiver fails to pay the consideration within the preset time, the asset ledger system can cancel the asset to be transferred and return it to the transferor . The undo rollback operation can be realized in the following two ways: Method 1: The second smart contract regularly detects, once the undo rollback trigger condition is met, the second smart contract automatically executes the transfer transaction that returns the assets to be transferred to the transferor. Method 2: The transferor or receiver initiates the return command of the asset to be transferred on the chain, and the second smart contract checks the trigger condition for canceling the fallback. If it is satisfied, it executes the return command of the asset to be transferred on the chain to generate the asset account address corresponding to the transferor. ...

Abstract

The invention discloses an on-chain asset transfer system and method through off-chain settlement, and relates to the technical field of digital assets. One specific embodiment of the system comprises: a transfer party asset application terminal system generating an on-chain asset transfer instruction, and then sending the on-chain asset transfer instruction with a transfer party signature to an asset account book system; the asset account book system executing a first intelligent contract contained in transferred asset information of the on-chain asset transfer instruction to generate to-be-transferred asset information; the receiver asset application terminal system generating a to-be-transferred asset transfer instruction on the first chain, and then sending the to-be-transferred assettransfer instruction on the first chain with the receiver signature to the asset account book system; and the asset account book system executing a second intelligent contract contained in the to-be-transferred asset information of the to-be-transferred asset transfer instruction on the first chain to generate transferred asset information. According to the embodiment, the complete transaction process of on-chain asset transfer and off-chain payment is realized based on the intelligent contract, and the transaction risk is reduced.

Description

technical field [0001] The present invention relates to the technical field of digital assets, in particular to an on-chain asset transfer system and method through off-chain settlement. Background technique [0002] At present, blockchain technology is developing rapidly. As a new decentralized computing paradigm, blockchain provides technical support for the operation of various digital assets on distributed networks. These digital assets run on the distributed network of the blockchain, do not rely on a specific third party or central party to keep accounts, but conduct global multi-node consensus accounting through shared ledgers, and achieve a technical guarantee through encryption algorithms security system. [0003] In the existing technology, the typical transaction mode of blockchain-based digital assets is: the transferor initiates a transaction, and transfers a certain amount of digital assets corresponding to its asset ledger address to the recipient's asset led...
